Advice?

So, I got interested in this guy (as a person, not romantically lmfao, had that misunderstanding already today) after seeing multiple of his posts and comments. So I DMed him because he seemed like a cool person. He says he has fun talking to me, and I call him my friend (I say stalker as a joke because I review his comments and posts often and harass him to sleep once in a while) but today, he called me a batshit insane bitch and when this guy said "f you, you seem creepy," "he just said "yea, no shit." I'm confused asf and genuinely my feelings are hurt. He also posted about me without my permission (I did it back but beside the point) and shared screenshots of our conversation. Sure, I may have called him a dumbass and revealed his irl name... so not entirely clean... but to be fair he did say he didn't really care whether his name got outed or not. Just.... idk should I stop bugging him if it's such an inconvenience for him? He'll probably see this, so as a message outward, I have low-spectrum autism so I don't actually understand a lot of social things and I'm pretty darn sensitive.
